I got a used 6.2 engine and have it mounted in my frame. I wanted to start it before I put all the sheet metal back on. (This is a restoration modification of an old military Jeep pickup).
I placed a 5 gallon diesel can under the front of the truck and stuck the input of the new mechanical fuel pump into it. I cranked the engine over to see if I was pumping fuel. I was not. A few pumps of a brake bleeder later I had the new mechanical pump primed. It pumps fuel when I crank the engine.
Next I loosened the screw on filter at the back of the intake. I cranked it until I saw fuel spraying out of the seal. I stopped and tightened the filter.
Next I loosened the hard injector line at the injector and cranked it until I saw the fitting getting wet. I tightened all the lines back up. I then removed all the glow plugs and cranked the engine over. I could see a mist coming out of the glow plug hole on #8.
I replaced all the glow plugs and tried to start it. It still does not start.
I am not using a glow plug controller. I currently am holding the glow plug wires to the positive side of the battery for about 6 seconds before I try to start the engine.
I know the glow plugs are all good. I have tested each one. I also get a nice spark when I touch the wires to the battery positive.
As far as I can tell the glow plugs are AC Delco 60g's. Should I be firing them longer than 6 seconds?
When I first tried to start it I could see some white smoke coming from the exhaust manifold. I don't see that anymore.
I do hear the IP solenoid click when I power that on.
Is it possible I still have air in the fuel line? What is a better way to bleed the air than what I have tried?
